Here lately I have been considering getting a informal target revolver in either 357 Mag or 38 Spl. I plan on shooting 148gr. DEWC with a light load (recommendation). What type of revolver would do me the best? I have 2 Ruger Blackhacks with 4-5/8 " barrel, but I don't think they would be right. Suggestions please. I don't know nothing about target revolvers, so be nice.
